WILLIAM J". BRADLEY, OF TROY, NEW YORK, ASSIGNOR TO THE RAIL JOINTCOMPANY,

OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

SHEARS FOB. METAL BARS.

Application filed January 18, 1912. Serial N 0. 671,938.

To all whom it may concern:

Be it known that 1, WILLIAM J. BRADLEY, a citizen of the United States,residing at Troy, in the county of Rensselaer and State of New York,have invented certain new and useful Improvements in Shears for MetalBars, of which the following is a specification.

The present invention relates to the subj ect of metal shearing and moreparticularly to an improved construction of shears for shearing metalbars of T-section or of approximately that form. To this end the invention possesses special utility in its application to the shearing ofrolled rail joint bars into rail joint lengths, and is designedparticularly for the purpose of effecting a practical improvement overthe present method employed for shearing rail joint shoe-angles of thetype that are employed in the well-known W'eber rail joint. Thisshoe-angle of the Weber rail joint includes a rail supporting basemember, an upright clamping or bolt plate member, and a spiking toe orflange that is pro ected outwardly from the corner of the bar where thebase member and upright member intersect. In those forms of the shoeangles where the said toe is narrow and has only a slight projectionfrom the upright member, little difiiculty is experienced in evenlyshearing or cutting up the lengths as they are received from the passesof the rolling mill. However, where the toe of the shoe-angle bar 18 sowide as to project outwardly from the upright member for quite adistance, when the ordinary shearing methods and apparatus are employed,there is a tendency to bend in the toe at the end of the piece that issheared, this bending in and distortion becoming greater as the depth ofthe toe 1s increased.

Accordingly, the main object of the invention is to provide a novelconstruction of shears which will enable metal sections of thischaracter to be effectively sheared without bending in or distorting thetoe, and which will thereby save the cutting of these shoe-angles with ahot-saw, or by making two operations of a shear.

lVith these and other objects in view, the invention consists in certainnovel combinations and details of construction as will more fully appearas the description pro- Specifieation of Letters Patent.

ceeds, the novel features thereof being pointed out in the appendedclaims.

For a full understanding of the invention, reference is to be had to thefollowing descriptlon and accompanying drawings, in which Figure 1 is afront elevation of a pair of shearing knives constructed in accordancewith the invention, the said shearing knives being shown in an openposition with a shoeangle section inserted between the same. Fig. 2 is aprojected edge view of the pair of shearing knives occupying thepositions shown in Fig. 1. Fig. 3 is a view similar to Fig. 1, of theknives showing the position assumed thereby when acting upon the sectionplaced therebetween. Fig. 4 is a view similar to Fig. 2, but projectedfrom Fig. 3 and illustrating the positions of the knives as shown inFig. 3. Fig. 5 is a view similar to Figs. 1 and 3 showing the positionof the knives at the end of full stroke, after the section has beensheared. Fig. 6 is a view similar to Figs. 2 and 4, but projected fromFig. 5 to illustrate the lmife positions of the latter figure.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Specifically describing the present em bodiment of the invention, thenumeral 1 designates the lower shearing knife, and 2 the upper shearingknife, the lower knife being usually fixed or stationary while the upperknife is mounted to move vertically. The lower knife is formed with apair of inclined cutting edges 3 and 4 which are arranged atsubstantially right angles to each other, the cutting edge 3 beingadapted to act from the underside of the base 5 of the shoe-angle, whilethe cutting edge 4 is adapted to act upon the outer side of the uprightmember 6 of the shoe-angle. It will also be observed that the lowerblade 1 is provided at the intersection of the cutting edges 3 and 4with a toe-holding socket 7, the base of which is arranged insubstantial alinement with the cutting edge 3, and is designed toreceive and support the toe 8 of the shoe-angle, the said cutting edge 3being extended along the lower side of the said socket.

The upper knife 2 is formed with a cut ting edge 9 arranged parallel tothe cutting edge 3 of the lower knife and adapted to cooperatetherewith. An inclined slot 10 is also formed in the upper blade for thereception of the upright section 6 of the shoeangle. The upper incliningside of this slot 10 is formed with a cutting edge 11 adapted tocooperate with the upright cutting edge at of the lower knife when theupper knife is forced downw ardly. It will also be noted that thecutting edge 9 of the upper knife is extended on the opposite side ofthe slot 10, as indicated at 9", for cooperation with the cutting edgeat the lower side of the socket 7 to act upon the toe 8 of theslioeangle-. Where the toe 8 of the shoe-angle is of a greater thicknessthan the base member 5 thereof, (as shown in the drawings), the cuttingedge 9 of the upper knife would be correspondingly ofiset from or out ofalinement with the cutting edge 9, thereby enabling all of the cuttingedges to be brought simultaneously into action when the upper knife islowered.

The base member 5 of the shoe-angle shown in the drawings is provided atone edge thereof with an upwardly extending shoulder flange 12, and a.corresponding holding notch 13 is formed in the upper blade 2, thebottom and upper side of the notch being-formed with a cutting edge 14adapted to act upon the flange 12. An inclined shoulder 15, upon whichthe shouldered edge of the shoe-angle rests, is pro- )vided upon thelower knife 1 at the upper end of the cutting edge 3. This constructionprovides means whereby the shoe angle is initially held out of positionupon the lower knife, and is only carried to final stationary positionthrough the movement of. the upper knife thereupon.

The shoe-angle is designed to be placed in proper position between theknives when the upper knife is raised, as indicated in Fig. 1, the basemember of the shoe-angle resting upon the cutting edge 3 of the lowerknife, the toe 8 being partially received within the socket 7 of thelower knife, while the upright member 6 is partially received within theslot 10 of the upper knife. The shoe-angle is then out of position uponthe lower knife, although, as the upper knife is forced verticallydownwardly, it moves in a diagonal direction with respect to all of thecutting edges, and the shoe-angle is gradually moved diagonally on thebottom knife until it is properly seated thereon. A continued downwardmovement of the upper knife brings the cutting edgesinto operation so asto simultaneously shear all three of the arms of the T-bar or shoe, theposition of the upper knife when shearing being indicated by Fig. 2.More particular attention is directed to the fact that all three arms ofthe bar or shoe are simultaneously and positively sheared in a directiondiagonal to all of said arms, thus effecting an even shearing operationthat secures a perfect severance of rail joint lengths of shoe-anglesfrom the bar that is received from the rolling mill, and also securingeven and perfect cutting off of, the toe projection or flange 8 of theshoe angle without bending or distortion thereof in the slightestdegree. This is especially safeguarded through the employment of thenovel shearing or cutting edge 9' that operates upon the upper side ofthe said toe from the outside of the upright member of the shoe, that isto say, independently of the action of the cutting edges 9 and 11.

From the foregoing it is thought that the construction and operation ofthe herein described improvement in knives will be read- 11y apparentwithout further description.

I claim:
